How to solve these 6 negative effects of stale air

Stale air is associated with unpleasant feelings in the indoor environment.

People often associate it with high concentrations of carbon dioxide (CO2). However, at low levels, it is not harmful to health on its own. Along with the concentration of CO2, the concentration of other substances in the air also rises, and it is these that cause the symptoms of stale air.

Carbon dioxide rises very similarly to them, but (unlike the other substances) it is easy to measure and is therefore a great indicator of indoor air quality.

Symptoms of stale air

NAUSEA AND DIZZINESS

 

Ideal solutions for the indoor environment

Measuring and ventilating is the foundation for a comfortable indoor environment and good air quality. This is especially true for dense urban development and areas with high outdoor air pollution. Monitoring and preferably subsequent control of ventilation will ensure ideal air quality in the indoor environment.
